l Application tiled July 12, 1916. Seril No. 108,872.

To all 'whonwftmay concern.'

Be it known that I, HAiioLD S. Moii'ron.y a citizen ofthe United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain 'new and useful Improvements in Vehicle- Brakes, of which the following is a specification.

My invention relates to vehicle brakes, particularly brakes for application toall four wheels of a power'driven vehicle such as an automobile, and has for its object to provide a novel equalizer' nieclianisii'u.with

means for adjustably supporting the saine on thc automobile or vehicle, suoli that in case oneof the brake rods should break the remaining brakes, whether one or three,V

Vthe equalizer `shown in Figs. 1 and 2- taken on lines 3-f3 of Fig. 1. lFig. 4 is an en larged plan view of mechanism shown in gy' inventionis most easily applied to automobiles and is shown 1n conjunction with an automobile having the usual rear wheel brakes and also having front wheel brakes,

asis illustrated in Figs. 1 and 2. A pair of longitudinal frame members 10 and 11, provided with springs 12 and 13, support la front axle 14 anda rear axle'l upon which are journaled, respectively, v.front steering wheels 16 and 17 and rear driving wheels 18 4 and 19. The rear Wheels l8.and 19 are pro vided with brakes 20 and 2l operated by brake rods 22 and 23, as is customary. As shown, the front Wheels also arel provided with brake meinbers and 3-1, of a special type which are described more in detail in a has secured to it at one endoutside of iframe. member 10 an arm 26 to which is pivoted.

the rod 23, andhas loosely mounted upon the other endl a Isleeve 25 passing through traine member I1 which is 'provided with an arin 27 on the outside thereof pivotally connected to the other brake rol 2Q and corre spending in position and extent to arin 26. Anctherarin 28 is secured to'shaft 9.4 n'ear the center thereof and is piilotally connected to an equalizer bar 29, which ,in turn is pivot-ally connectedto a similar arm 30 sir cured upon the inner end of the sleeve4 This 1i-m28, and by it the equalizer 129, is connected as will hereinafter be pointed out with the usual foot `pedal 31 inoui'ited on shaft 32 journaled in the frame members 10 and 11 toward the front of the vehicle.

lVithout going into detail as tothe character of the front Wheel brake mechanism, it may be said that the drums or 3-1 are engaged on the inside by a brake band 62 which is operated by an arm '67. ln double-v armed castings 75, 76, secured to front axle 14, are journaled shafts 84 having fast thereon arms 85 Which engage the arms (i7 for actuating `the front brake bands 62 in a manner which need not be here described..

The arrangement of brake-actuating and. equalizer mechanism, whereby the` 1several brakes may be simultaneously and equalizingly set, even though one ot' the brake rods should be .disconnected or broken, is as tollows: A pair of castings 91 and 92, shown in Fig. 1, and in detail in Figs.' 3 and Ll, in part support this meehanisin. These castings each comprise bifiireated base portions 90 which clasp the lower flange of the respective frame members 10 nd 11 and which are held in place thereon by a pairof` set screws 97 screwed therein. `Ear 93 formed integral with said base has screwed in it a. suspending rod'or support94. A pair of bearings 95,v 96 are adjustably mounted upon the support 94'and have jonrnaledA vtherein a transverse shaft 98 which extends across the vehicle frame. Loosely mounted' on one end of the shaft 98 is a sleeve 99` which rhas secured to its end' adjacent tie4 bearing 96 a depending arin 100v connected to arm 100. is secured to Y'the shaft 9S near the opposite end thereotl and is connected by a link 104 to an arm 105 on the shaft 84 opera-ting the brake on wheel 16. Shaft 08 has secured to it near the center thereof an ioo 4 opstanding arm 10G, which is ivotally connected at one end to an equa lzer bar 107, Said bar in turn being pivotally connected to asimilar arm 108 on thc end of sleeve 5m. A triangular connector plate 10U, which Serves as a central equalizer between Vthe two sets of brakes` i5 piroted at one point to theI `equalizer bar 107 and is pivotally connected at another point below said equalizer bar h v means of a link 110 with the central portion 0f equalizer 2t) controllihg the rear wheel brakes. A lilik 111 is pivoted to a 'forwa rd portion of the equalizer' 10U and connects with the foot pedal 2&1.

The advantages ot' my invention are very obvious. It will be seen from the above that when the foot pedal 31 is operated the power transn'iitted through link 111 and equalizer 109 will be in the aggregate equalized between the front and the rear braking members. In turn the power going to the front or rear wheelsl will be equalized between the pairs of wheelsA It follows from this that if the connecting rod 11() were to break, or any of rods 12;), Z' 1H]` lll-t were to break, that the power would nevertheless be transmitted to the remaining connecting .brakes, equalizer plate 109 merely rshitting,r

in position in ease rod 110 were to break. There would. therefore,` be only one rod or link'which could break .so as to render the brakes inoperative, and that is the .short main link 111, which can be made strong enough to offset any breakingr tendency.
